I bought this non-slip pad for my 4 year old Morgan filly who has a very round back and barely any withers. I've tried just about every size saddle I could get my hands on trying to find one that wouldn't slide around. It got to the point that we couldn't do any serious work because the saddle kept slipping and knocking the both of us off balance. And i didn't want to go out and have a saddle professionally fitted because she is still a baby and has a lot of growing left to do! So I found this pad online, and for such a great price I just had to give it a shot. To my amazement, it worked incedibly! I can use it with my dressage, hunt and western saddles and not one of them slips on her! I even used it at her very first show, and with all her spooking I was very glad to have it! The only reason I didn't give it 5 stars is because its not the most durable thing, and it already has a minor tear in it. But for that price (compared to others I've found) I'm definitely okay with it! I will be sure to order this again!
